Referring to the drawings, the calculating machine having two slides, asillustrated, is arranged within a casing 1, which is pivoted in brackets4, 5 of a supporting frame 6'by gudgeons 2, 3 provided at the end facesof the casing. The supporting frame -6 1s provided at one end with aspring-actuated pin 7, and the end wall of the casing 1 opposite thispin is provided with corresponding holes 8 into which the pin 7 can snapto secure the casing 1 in a desired angle of inclination.

The calculating machine proper consists substantially of a setting plate9, a slide 10 located above the plate and a slide 11 located below saidplate. Beneath the setting plate 9 is located the actual drivingmechanism which can operate simultaneously the two slides 10 and 11.

The setting pZate.The setting plate 9 (Fig. 1) is made from a cast ironplate 12 ,(Fig. 8) provided toward the end at the left hand as seen inFig. 1 with slots 13, for the reversing levers, a slot. 15 for thezerosetting handle and with a plurality of slots 16, in the present casenine, in which the setting knobs slide. The plate 12 is further providedwith a bore through which the driving crank shaft is assed. In the slots16 slide setting knobs 1 (Fig. 1) provided with indicating arms orpointers 18 which, cooperating with a correspondingly arranged scale ofnumerals, indicate the setting. The ends of the setting knobs 17 locatedbeneath the plate 12 support carriers 19 (Fig. 8)

which are provided with two adjacent recesses 20 in order to. entrainthe driving wheels of the counting mechanism. The

knobs 17 are coupled in any suitable way not shown on the drawing withnumeral disks, the numerals of which are seen through the apertures 31in the plate 12 and agree with those indicated by the pointers 18 (Fig;1). The numerals appearing in apertures 31 and the setting knobs 17 maybe returned simultaneously to zero position by actuating handle 34. Thiszero setting mechanism does not however form part of the present invention, and therefore is not-particularly pled so that each. can beused independently of the other. In such calculating machines as may beintended for less complex calculations the lower slide 11 may bedispensed with, in which case the construction of the driving devicesfor the counting mechanism is also simplified to the extent that onlyhalf the number of driving spindles for the counting mechanism isrequired.

1 The upper slide (Fig. 9) consists of acasting 39 provided with lateralguides 40. The part 39 is furnished with two longitudinal series ofsmall wheels, that'is'to say, a set of wheels for the product which givethe re'-, salt on the slides, and a set of quotient wheels which renderpossible a control of the number of, revolutions of thecrank The productwheels 41 consist of numeral disks 42 and spur wheels 44 meshing withspur wheels 53, the last named spur wheels being,

in mesh with actuating spur wheels 90 (Fig. 4). The spur wheels 44 areprovided with cranks 45 (Figs. 5 and 9) which are adapted to cooperatewith the controlling levers for the tens transfer. Y On the same face ofthe having numeral disks 57 are apportioned to spur wheels 44 there aremounted heartshaped cams 46 forming partof the zero setting mechanismfor the counting-wheels,

forming no part of this invention, and there fore not described indetail. The actual position of the product wheels can be read throughapertures 72. The quotient wheels a part of the product wheels only;they can be reset to zero position by actuating the longitudinal shaft68 by handle- 71. This also resets the product wheels 42 by means ofcrank arms 70 cooperating with cams 46 and with similar cams of, thequotient wheels (not shown in detail). v

Actuating nwchandsr m.-Below the guides the intermediate wheels 53 (Fig.9) for the product wheels, and which are rovided at one side with bevelwheels 91 igs. 3 and 6) which engage with the one or the other of twobevel wheels 92, 93 on a sleeve 94 so that the spur wheel 90 is rotatedeither to the left or to the right. The sleeves 94 slide axially uponspindles 95, 96 arranged alternately, the spindles 95 hereinafter termedcounting train spindles, operating on the upper slide 10, while thecounting train s indles 96 operate on the lower slide 11. hen themachine is provided with one slide only the spindles 96 as well as theportion connected therewith of the device for driving the counting trainare obviously omitted. The sliding of the sleeves 94whereby either thebevel wheel 92 or the bevel wheel 93 is brought into engagement with thebevel wheel 91 on the s ur wheel 90, is effected by reversing arms 9 98respectively provided with knobs 99, 100, projecting through thecorresponding slots 13 and. 14 beyond the setting plate 9 (Figs. 1 and4). The re: versing arms 97 and 98 operate, through the medium 'ofsuitable intermediate members, rotatable spindles 101, 102 provided withforks 103 which engage in an annular groove I in the sleeves 94 so as'tomove the sleeves toeach provided i recessed portions 20 of the carrier19 of the.

corresponding setting knob 17 can en age (Figs. 1, 3, 8). 'Each spindle95 an to the corresponding bevel wheel sleeve 94,

with aspur wheel 111, 112 axially rigid and brought into operation onthe tens transfer, the mode of operation of which will be ex-. plainedhereinafter. The ends of the spin dles 95 remote fromthe spur wheels 111rest in a bearing plate 113 through which the spindles 96 are passed, alikeplate 114 being provided for the free ends of the spindles 96. Whenthe spindles 95 or 96 are turned they transmit their motion through. themediuniof the bevel wheel sleeves 94 to the spur wheels 90 and thencethe intermediate wheels 53 of the product wheels of the 'slides '10, 11,whereby in a well-known man- 'ner with one slide, or with both slidessimultaneously, one or two kinds of calcula-.

be carried out. This mode of using tion can a calculating machine withone or two slides 113 is further respectively provided, adjacent isperfectly well known and for that reason no further explanation is hererequired.

The driving of the spindles 95 and 96 through the medium of the spurwheels 107 and 108 is effected by a number of racks 115 whichreciprocate, and which are periodically brought into the path of thespur wheels 107 108 so that those spindles 95, 96, the correspondingspua' wheels 107, 108 of which have been moved out of zero position bythe corresponding setting knobs 17, are driven in a correspondingmanner.

According to the present invention, a graduated speed is imparted to theracks 115, by giving each one separately a stroke corresponding to thenumerical value appropriated thereto; that is to say, the rack 115 towhich the number 9 is appropriated travels at a rate of speed nine timesas great as that at which the rack to which the number 1 isappropriated, and so on. manner, when using the lower number during arevolution of the crank a lower absolute working speed in thecounting-train driving-devices is attained resulting in a reduction inshock and Wear and tear present in previous machines in which'the samespeed is apportioned to the driving devices for all the numericalvalues.

The whole of the racks 115 which rotate the spindles 95, 96 are mountedupon a rack carriage 116, .formed substantially of two side portions 117connected together by transverse members 118. The side portions 117 areprovided with inclined slots 119 in which slide rollers 120 rotatablymounted on the machine casing. Each of the side portions 117 supportsfurther a pair of rollers 121 which cotiperate with driving cams 122.The circumference of each of these cams is formed with two semi-circlesof different diameters. lVhen the carriage during the first half of arevolution of the crank operates in conjunction with the portion of thecircumference of greater radius, it and the racks resting upon it areraised during the travel in the slots 119 whereby the racks can engagewith the wheels107, 108; whereas when the rollers 121 engage-with theperiphery of smaller radius the rack carriage is lowered. The twodriving cams 122 are connected together by a number of eccentric disks123 arranged side by side, the lowest one, as seen in Fig. 12. beingarranged concentric with the axis of rotation of the disk 122, while theremainder in succession have a graduated increase in eccentricity, sothat the eccentricity of the second lowest eccentric disk 123, as seenin Fig. 12, is therefore 1/9 of the eccentricity of the highesteccentric disk 123. Each of these eccentric disks 123 is in linkedconnection with a rack 115 by means of an eccentric strap and rod 124,125. \Vhen, as a result of the rotation of the cam disks 122, a risingand falling mo- In this olution of the crank, it therefore follows thatthe racks 115 for the lower numbers are moved considerably slower thanthe racks for the higher numbers. Shocks and the like are in this wayavoided, and the wear of the moving parts considerably reduced. Only thefirst rack 115 located in front has no to-and-fro movement imparted toit, and it travels with the carriage without any movement relativethereto in the path formed-by the slot 119.

On the front cam disk 122 is mounted a bevel wheel 126 meshing with abevel wheel 127 which is mounted on the lower end of the main drivingspindle .128 (Figs. 2 and 12). The spindle 128 further carries a. bevelwheel 129 which by means of bevel wheel 131 on spindle 132 (Fig. 5),bevel wheels 9201- 93 on sleeve 94 and bevel wheel 133 drives thequotient numeral disks 57 in a manner which needs no description andillustration in detail, as it forms no part of this invention and can beeffected by an expert in any suitable way.

' WVhen the driving crank 130 is turned the rack carriage 116 is raisedduring the first half of the revolution while the racks 115 moveto-and-fro with respect to the rack carriage. ()n the upward movementthose spur wheels 107 and 108 on the spindles 95, 96 which have been setby the knobs 17 are brought into engagement with racks 115 appropriateto their numerical value, whereby they are rotated so that the numericaldisks 42 of the product wheels are turned round to the extent of as manytenths of the circumference as may correspond to the numerical value inquestion to which the spur wheels 107 and 108 were set by their knobs17. On each setting of the knob 17a drive is effected toward both theslides, and by means of driving devices entirely independent of oneanother. Those spur wheel 107, 108, which were not moved from the zeroposition by the setting knobs 17, engage pon the raising of the carriagewith the zero rack which has no reciprocating movement upon the rackcarriage, and thus look their spindles 95, 96 against inadvertentrotation as at this moment the locking device for the tens transfer isout of engagement (Figs. 21 and The locking of the spindles 95, 96during the movement of the slide is effected by a plate 140 on arms 139ivoted at 138 (Figs. 3 and 4). The plate 140' so as to release the spurwheels 90 and enable the machine to be again used.

The tens transfer.-The forward movement of the counting mechanism of theslide for thenext higher denomination, as a product wheel of. a lowerdenomination passes from 9 to 0, is effected in a machine according tothe present invention by the reciprocating racks on the rising andfalling rack carriage 116, and advantageously by that rack which has thelongest stroke, viz. the 9 rack. With the object of driving the tenstransfer devices, this rack is provided with a pin 143 (Figs. 16 and 17)which slides in a vertically slotted guide 144 on a rack 145 carried onthe machine frame so that the 9 rack.115 imparts a reciprocating motionto the rack145, while the pin 143 moves up and down in the slotted guide144. The rack 145 works in gear-with the spur wheels 146 (Figs. 16 to23) ofawhich one is arranged for each spindle 95 at the.

side of the-slide 10 and one for each spindle at the side of the slide11 (Fig. 3). Each spur wheel 146 is connected with a pin 147.

provided between its bearing ends with a slot 148 in which a lever 150is pivoted on a pin 149 so as to be capable of vibration in thedirection of the axis of the pin 147. Each lever 150 is provided with alateral arched guide face 151 and with an upper arched surface 152, thelatter being provided with an angular recess 153. The vibrating levers150 are subjected to the influence of springs 154 by means of which theyare generally held in a normal position shown in Fig. 17 As may be seenin Fig. 20 of the drawings, each lever 150 is angularlydisplaced withrespect to the lever of the preceding denomination to a certain extent,which however, does not permit of a greater difference than 360 betweenthe position of the last and the position of the first levers, and theextent is generally considerably less.

Longitudinal spindles 155 below the slides 10 and 11 and upon whichthree-armed levers 156 are rotatably mounted extend from one end wall ofthe casing 1 to the other. Each of the levers 156 consists of a leverarm 158 provided with a rounded upper end 157, a depending lever arm 160provided with an end having two faces converging to a point 159, and anarm 161 located in the plane of vibration of the lever 150 and providedtoward its outer end with inwardly bent extremities 162 (Figs. 3 and18). Adjacent each lever arm 160 there is arranged a spring 163provided, opposite to the converging faces 159 of the lever arm 160,with an angle-piece 164, the sides of which make contact with one or theother edge of the end 159, so that the control lever 156 is held eitherin its position of control or in its normal osition. The pivoted lever150 opposite'tlieend 162 are provided with a recessed portion 165 sothat in the normal position of the lever 156 (Fig. 18) it is free tovibrate without being affected by the lever end 162. The levers 1 58 and161 are relatively displaced with respect to the vertical plane, eachlever end 157 lyin in the plane of rotation of the cranks 45 o theproduct wheels, while the corresponding lever end 162 lies opposite thatpivoted lever 150 which is appropriate to the counting mechanism of thenext higher denomina-' tion.

At the side of both slides .and above the toothed plates 145 there areconnected with the carriage 116 plates 166 carrying arms 167 pivoted at168. Each arm is provided with two pins 169 and 170, the latter of whichin the lowered position of the carriage 116 lies within the spacesbetween the teeth on the spur wheels 111 mounted on the counting-trainspindles 95, 96. The arms 167 are provided at the lower end with aninclined surface 171 and a pin 172 projecting to the rear. With this pinthere is generally in engagement the hook-shaped end 173 of a lockinglever, 174 pivoted at 175 on the machine frame (Figs. 20 to 23). Thelevers 174 have further small lugs 176 projecting laterally from thehooked end 173 and are subjected to the influence of springs 177 whichtend to rotate the .levers 174 in the direction of the clock. Thepivoted arms 167 are provided adjacent to their pivot pins arranged onthe machine-frame pins 179.

Further, a stop-pin 180 is provided at one side of each arm 167 [orlimiting the outward swing of the arm. Beside each pivoted arm 150, onthe machine-frame, are provided curved rigid guide-pieces 181 (Figs. 16and 17).

Behind the crank arms 160 of the control levers 156 there passes in themachine-frame a longitudinal spindle 182 (Figs. 5, 18, 19, 26 and 27),which is provided opposite each crank-arm 160 with a pin 183. Thespindle 182 is 122 (Figs. 11 and 27) with a rigid arm 184. The spindle182 is subjected to the influence of a spring 185 having one endattached to the frame of the machine, and tending to turn the spindle soas to move the pins 183 out of contact with the crank-arms 160. Each ofthe cams 122 is provided with a rovided at the end facing the camspreferably adjustably arranged striking-pin 186 Which, during therevolution of the cam 122, at a given moment comes into contact with oneend of a double-armed lever 188 pivotally mounted upon a pin 187, whilethe other arm of said lever rests on the crank arm 184 of the spindle182.

The mode of operation of the above-described device is as follows:Normally the pivoted arms 167 are in the position shown Fig. 18 inwhich they are free to swing past the curved ends 162 of the lever arms161.

As the rack 145, which drives the spur without vertical movement, itfollows that the whole of the pivoted arms 150 swing toand-fro during arevolution of the main driving-crank 130. The pivoted arms 167 duringtheir up and down movement with the carriage are secured by thelockinglevers 174, the pins 172, during the up and down motion of thecarriage, sliding along the lower edge provided between the projectingportion 176 and the hook 173 on the locking-lever 174 which is immovableon the machine frame in the vertical position.

As a product wheel moves over from 9 to 0, the crank-arms 45 of theproduct wheels are brought into engagement with the ends 157 of thecontrol levers 156 causing the levers 156 to rotate somewhat, whereuponthe parts take up the positions shown in Fig. 19, the control leverafter movement being held by the anglepiece 164 on the spring 163. Bythis rotary movement the bent end 162 of the lever arm 161 arrives inthe path ofthe curved surface 151 of the pivoted arm 150 of the nexthigher denomination, so that when this pivoted arm passes the end 162 itis partially rotated about its pivot 149 against the influence of itsspring 154, whereby the curved upper surface 152 is brought under thelug 176 of the locking lever 174, and the recessed portion 153 into thepath of the inclined edge 171 of the pivoted arm 167 (Figs. 20 to 23).This takes place while the carriage is in its lowered position and therack is on its return stroke. As a consequence of the contact betweenthe surface 152 and the lug 176, a rotary movement of the locking-lever174 takes place so that the hook 173 is removed from the pin 172, thusreleasing the pivoted arm 167. As the pivoted arm 150 moves farther, therecessed portion 153 meets the cdge'171 so that the pivoted arm 167rotates, whcreupon'the pin 169 is broughtto bear upon the spur wheel 111which then imparts a forward movement to the corresponding product wheelto the extent of a single number (Fig. 22). The outward swing of thepivoted arm 167 is then limited by the stop pin 180. \V hen the carriageagain rises, after a tens transfer has been effected, the guide edge1'78 slides over the pin 179, thus imparting to the pivoted arm 167 apositive rotary movement during which the pin 172 passes over the outeredge of the hook 173 so that the locking-lever 174 is rotated againstthe influence of its spring 177, while the hook 173 again snaps over thepin 172, thus again securing the pivoted arm until the next tenstransfer is to take place.

As a consequence of the relative angular displacement of the pivotedlevers 150, the pivoted arms 167 come into operation one after anotherat different times, so that a false transfer is avoided. As soon as thelast pivoted arm 150 has passed the curved end 162 of its lever arm 161,the pin 186 (Fig. 27) passes one end of the lever 188 causing it tovibrate, so that the spindle 182 is rotated by the crank-arm 184 againstthe influence of the spring 185. The pins 183 are thereby brought intocontact with the adjacent edges of the lever arms 160 returning thewhole control lever 156 to its normal position. As soon as the normalposition has been again taken up, the pivoted arms 150 are swung back totheir normal position under the influence of the springs 154. Thosepivoted arms which for any reason stick fast in their slots 148 so asnot to be pressed forward by their springs 154, arebroughtintoengagement at the next pass with the rigid guide-piece 181, andpositively returned thereby to their normal position.

It remains to be noted that the controllever 156 appropriated to thehighest denomination is provided with a clapper 189 Instead of alever-arm 161, so that a gong 190 is sounded in the usual manner as'themachine is about to go beyond the highest number, for which it isarranged.
